How Do Ductless (Mini-Split) Air Conditioners Work

People are so used to central air conditioning that they often have a hard time envisioning how a ductless mini-split system can cool their Glenwood Springs, Aspen, or Vail, CO home. I want to assure you mini-splits can do just that, and they offer several advantages over traditional forced air systems.

What are they and how do they work?

At their heart, ductless mini-split air conditioners use the same technology as the air source heat pumps used in millions of central cooling and heating systems. They don’t need ducts because mini-split systems have indoor air handlers connected directly to an outdoor compressor/condenser. The indoor and outdoor units are linked through electrical and refrigerant lines requiring just a single three-inch hole through an outside wall. This allows the air handlers to deliver the conditioned air directly to specific rooms or areas of the house.

But are they whole-house systems?

Yes, they are. As many as eight air handlers can be connected to a single outside unit and each can be set to a different temperature for complete comfort control. This is a great way to save energy by not cooling rooms that aren’t being used.

Is ductless really better?

Consider this: With traditional central HVAC systems, ductwork can waste up to 30% of the conditioned air because it never makes it to the rooms in your house. The reason can be ductwork issues like leaks, bad design, and poorly insulated ducts. Mini-split systems deliver the conditioned air directly to the rooms where it’s needed thereby cutting your monthly utility bills. This makes a ductless mini-split air conditioner the perfect choice for homes with radiant heat or new additions that aren’t connected to the existing ductwork. 

This sounds too good to be true

There are certainly some things about a mini-split system that can be considered drawbacks. It will cost more upfront than a traditional central air conditioner, especially if you already have ductwork installed in your Glenwood Springs, Aspen, or Vail, CO home. The air handlers are typically mounted on the interior walls and some people don’t like the looks aesthetically, but there are many styles to choose from to limit those concerns.
